thanks for the answers, but I need to know how to solve the problems, so I can finish the remainder of my homework.

Use a power of ten to change each to a decimal.

2 1/2 4 1/25
I need to learn how to solve these types of problems. I was out of the room when the teacher explained. Please help



What do you mean "power of ten"?

Are you talking about scientific notation?


-16g+3h-19h-4g
simplify the expression by combining like terms.

well

2 and 1/2 is 2.5 x 10^0
4 and 1/25 is 4.04 x 10^0


4-3x=16
